Not only have multiple independent researchers demonstrated that global temperatures are likely greater than at any period in the last 2000 years, but the data used by researchers are all independent too. Sources as varied as marine sediments, corals, tree rings, stalagmites, boreholes, the length of glacial tongues, ice cores, and lake sediments all independently confirm that modern global temperatures are anomalously high. Independent researchers using independent data and methodologies to reproduce the each other’s results is the ideal for how to conduct good science.

So very good. This is what popular science writing is all about.(via globalspin)
